Abstract: An electrophotographic photoreceptor includes a conductive support, a photosensitive layer on the conductive support, and a protective layer on the photosensitive layer. The protective layer includes a binder resin, metal oxide particles, and fluororesin particles. The metal oxide particles include, on a surface thereof, a first surface-treating agent including fluorine atoms, and a second surface-treating agent including a polymerizable reactive group and a hydrophobic group. At least some of the metal oxide particles are supported on a surface of the fluororesin particles. The fluororesin particles are fixed to the binder resin via the at least some of the metal oxide particles supported on the surface of the fluororesin particles.

Abstract: A semiconductor memory device operate during a program verification operation to apply a read voltage to a word line and a pre-charge voltage to a bit line in order to provide output data. A number of fail cells is determined in view of the output data, wherein the number of fail cells is directly related to an increase in voltage on a common source line (CSL) connected to memory cells providing the output data. During a subsequent program verification operation, the level of at least one of the read voltage and the pre-charge voltage is adjusted in response to the number of fail cells.
